• Critical for preventing contamination of clean water supplies, especially when chemicals or fertilizers are used.

Protects Irrigation Equipment

• Prevents back-pressure from damaging
• Centrifugal or submersible pumps
• Filters
• Drip/sprinkler heads

Maintains System Efficiency

• Helps retain water in pipelines after pump shutdown.
• Reduces the need for re-priming pumps, saving energy and time.

Supports Fertigation and Chemical Injection

• Stops injected chemicals from flowing backward into the main line or water source.
• Ensures safe and efficient application of nutrients.

Prevents Water Hammer

• Minimizes pressure surges in the line when water suddenly stops or reverses, protecting valves, joints, and emitters.
